Biography
John Robert Bolton was born in Baltimore, Maryland in 1948, and he served in the US Army Reserve from 1970 to 1976. He went on to work as a lawyer during the 1970s and 1980s, and he worked in the State Department, Justice Department, and USAID during the Ronald Reagan and George H.W. Bush administrations as a protege of US Senator Jesse Helms. From 2001 to 2005, he served as George W. Bush's Under Secretary of State for Arms Control and International Security, and he went on to serve as Ambassador to the United Nations from 2005 to 2006; as a recess appointee, he was forced to resign in December 2006 as it became unlikely that the new Democratic US Senate would vote to confirm him. Bolton was an early supporter of the Iraq War, advocated for regime change in Iran, North Korea, Syria, and Libya, supported foreign wars, and held nationalist and neoconservative views. In April 2018, he was appointed to serve as President Donald Trump's National Security Advisor, and he cut NSC personnel to under 300 and became an enemy of the International Criminal Court due to its lack of checks and balances.
